Can not install gfortran via homebrew

Question

I got this message when i tried to install gfortran.

~$ brew install gfortran
Error: No available formula for gfortran
GNU Fortran is now provided as part of GCC, and can be installed with:
  brew install gcc

My question is how to install gfortran with homebrew or port?

or

If now GNU Fortran is a part of GCC How can i compile fortran code using gcc?

I'm not sure may be i've misunderstood something i remember that the last time i still can use gfortran to compile my code but now it doesn't work.

Further information:

when i use command brew list i still see that gfortran is there but can not use it.

Further information (latest):

ok, now i can use gfortran command but another problem come

~$ gfortran-4.9 hello.f

Just do brew install gcc per the instructions. The gcc package contains gcc, g++, gfortran etc.

It appears that cloog is not installed or is not correctly linked into Homebrew's prefix. Please post the output of brew doctor to Gist or a pastebin and link to it. – Winfredwinfrey
